To give you a string that allows you to find the longest continuous palindrome that exists.Problem-solving idea: The string is added to the array first, and then solved with the suffix array. Two methods: 1, enumeration rank, directly compare rank the same string where the difference is not Len. If yes, the record is solved; 2, enumerate the addresses, and find the maximum value of the 2*len-i+1 and the LCP of the first address.PS: It is important to
Give a number, well, it's not a number, it's a bunch of numbers,
Like 98237482340328490328490324893024, a very long number.
To find the next palindrome, this palindrome is larger than the current value (not equal to).
Such as:
9 9 9 9->1 0 0 0 1
1 2 3 4 5->1 2 4 2 1
The algorithm time efficiency is O (n), where n refers to the number of digits, not the number, such as 123456789, only 9 bits, then the

Example 1:Given words =["bat", "tab", "cat"]Return[[0, 1], [1, 0]]The palindromes is["battab", "tabbat"]Example 2:Given words =["abcd", "dcba", "lls", "s", "sssll"]Return[[0, 1], [1, 0], [3, 2], [2, 4]]The palindromes is["dcbaabcd", "abcddcba", "slls", "llssssll"]Credits:Special thanks to @dietp
